Yes I have seen that in one-file-system.log

As I am root inside the chroot, I have done
make check -C tests TESTS=rm/one-file-system VERBOSE=yes

Test work
[chroot-i486] root:/usr/src/coreutils-8.0$ make check -C tests
TESTS=rm/one-file-system VERBOSE=yes
make: Entering directory `/usr/src/coreutils-8.0/tests'
make  check-TESTS
make[1]: Entering directory `/usr/src/coreutils-8.0/tests'
make[2]: Entering directory `/usr/src/coreutils-8.0/tests'
PASS: rm/one-file-system
=============
1 test passed
=============
make[2]: Leaving directory `/usr/src/coreutils-8.0/tests'
make[1]: Leaving directory `/usr/src/coreutils-8.0/tests'
make: Leaving directory `/usr/src/coreutils-8.0/tests'

The problem could be shorten to
> mount --bind /dev/shm/tmp10767 a/b
...
> + umount /dev/shm/tmp10767
> umount: /dev/shm/tmp10767: not mounted

mount think a/b is mounted, not /dev/shm/tmp10767


If that matter
[chroot-i486] root:/usr/src/coreutils-8.0$ mount --version
mount from util-linux-ng 2.16.1 (with libblkid support)

[chroot-i486] root:/usr/src/coreutils-8.0$ ls -l /etc/mtab
lrwxrwxrwx 1 root root 12 Oct 18 09:42 /etc/mtab -> /proc/mounts
